Abstract:
Mosque is very important in every society according to religious point of view. Masjid-eMuhammad presently known as station mosque of Risalpur. This mosque constructed in 1983
and renovated in 2013. This mosque is located in seismic zone location 2B with peak horizontal
ground motions from 0.16g to 0.24g.
An earthquake of magnitude 7.3 struck northern areas of Pakistan on 26 October 2015. Due to
this earthquake most of the walls of mosque got severe cracks.. This research was undertaken to
characterize the site conditions, study of causal factors and to evaluate the remedial measures.
This research involves soil-structure interaction investigation including attenuation of bed rock
time history using all soil properties determined from lab and field testing. Original bed rock
waves were derived from USGS at Kabul station and then used probabilistic seismic hazard
analysis technique for acquiring the waves on Risalpur bed rock. The analysis for attenuation of
waves was done on software ‘DEEPSOILS v6.1’.
The analysis of earthquake waves showed that wave’s amplitude increased from bed rock to the
base of structure. Using these waves we analyzed the critical wall of mosque on software ‘UDEC
5.0’. From this analysis we find the structural reason for cracks has been found from this
analysis. On the basis of these causal factors we suggested remedies and then analyzed remedial
solutions using software ‘PLAXIS’. The author believe that research will enhance the
understanding about geotechnical earthquake engineering, dynamic soil structure interaction and
in preserving the infrastructure of Commercial social use
